我们要开发一个简单的B2C商城，能够完成商品显示，购物车功能，订单流程就可以了，数据库我们使用SQLServer2005。数据库中有商品表，订单表，订单明细表，会员表就可以了，
数据库模型如下：
其中要说的一个就是：订单表的工作流ID，我们后面要使用工作流，所以这个工作流的ID是必须的。

对应的SQL语句如下：
[UserID] [int] IDENTITY(1,1) NOT NULL,
[UserName] [nvarchar](50) NULL,
[UserPwd] [varchar](32) NULL,
[Email] [varchar](150) NULL,
[RegIP] [varchar](15) NULL DEFAULT (getdate()),
[RegTime] [datetime] NULL,
CONSTRAINT [PK_MEMBERS] PRIMARY KEY CLUSTERED
(
[UserID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY],
CONSTRAINT [AK_KEY_2_MEMBERS] UNIQUE NONCLUSTERED
(
[UserName] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
END
